Stimulation of proteolysis on calmodulin
Life Sciences, 1990The proteolysis of calmodulin by fungal protease (type XIX) was greatly enhanced in the presence of dGTP and MS2 RNA. Whereas, only moderate proteolytic activation on bacterial proteases (type XXVI) was observed in the presence of MS2 RNA. No appreciable proteolysis of calmodulin by bacterial protease (type IX) was observed.

Proteolysis in Bacterial Sporulation
1980Publisher Summary Endospore formation and germination in various Bacillus species provide attractive experimental models for the study of cellular differentiation. These bacteria offer the advantages of easy cultivation and physiological manipulation, the possibility of genetic analysis, and a well-defined, relatively simple unicellular ...

Peering into proteolysis with presenilins
Journal of Alzheimer's Disease, 2001Presenilins were originally identified because they cause a neurodegenerative disease, but the impact of these proteins on the neuron appears to extend beyond neurodegeneration and into fundamental concepts of cell biology and development. Presenilins were identified as a result of the steady march of molecular genetics which first lead to ...

Proteolysis and Sterol Regulation
Annual Review of Cell and Developmental Biology, 2002▪ Abstract  The mammalian cell continuously adjusts its sterol content by regulating levels of key sterol synthetic enzymes and levels of LDL receptors that mediate uptake of cholesterol-laden particles. Control is brought about by sterol-regulated transcription of relevant genes and by regulated degradation of the committed step enzyme HMG-CoA ...

Hsp70s and lysosomal proteolysis
Experientia, 1994Confluent cultured cells activate a lysosomal pathway of polypeptide breakdown in response to withdrawal of serum growth factors. The substrates for this proteolytic pathway are a restricted class of cytosolic polypeptides containing peptide sequences biochemically related to lysine-phenylalanine-glutamate-arginine-glutamine, or, in single amino acid ...

Ozone and Pulmonary Proteolysis
Annals of Internal Medicine, 1970Excerpt To the editor: In their editorial on antitrypsin deficiency Falk and Briscoe (Ann Intern Med72:427-429, 1970) point out that intrapulmonary proteolysis might be due to either decreased inhi...
